the result i got after a quick google search:
A rare condition in which the blood doesn't clot in the typical way when a person bleeds.
With hemophilia, bleeding might go on for a longer time after an injury than it would if the blood clotted properly. Often, small cuts aren't much of a problem. But serious forms of the condition raise the risk of bleeding inside the body. This can damage organs and tissues. The main risk factor for hemophilia is to have relatives who also have it.
